Ahead of next week’s formal unveiling of the highly anticipated successor to the iPhone 4S, a new video has surfaced from China demonstrating the key differences between the forthcoming model and the iPhone 4S, while simultaneously confirming previous leaks, such as the new dock connector, larger higher resolution display and redesigned bodyshell. Of note is that the device will boot as normal, but will halt with a screen warning that the device is not registered with Apple’s developer program, suggesting that while the device is finished, the proper software had yet to be loaded onto the phone.
